"Didn't realise I was using the wrong size flange! Decided to purchase a smaller one and I feel like I've been pumping more milk since :)" says Chetna.
"I originally brought the pump with a 24mm shield but was a little big so brought the 21mm and is much better for me. Easy to use and very comfortable :) thanks!" says Alice.
"Lost my shield in a house move. Love that I could order it separately because we had everything else but... So, was perfect!! Love the feel," says Hineiokaia.
Why You Need the Right Size Shield
- Proper Fit Increases Milk Output: Chetna noticed she's "pumping more milk" just from switching to the correct size. Right fit creates optimal suction.
- Prevents Soreness & Cracking: Wrong size causes nipple rubbing and pain. Correct size prevents damage and makes pumping comfortable.
- Creates Proper Seal: Shield must sit fully on breast with no air gaps for effective suction. Right size ensures proper seal.
- 3 Sizes Available: 21mm, 24mm, 27mm—find your perfect fit.
- Soft, Comfortable Silicone: Gentle against skin for comfortable pumping sessions.
- BPA & DEHP Free: Safe, non-toxic materials for you and baby.
- Compatible with Wearable Pumps: Fits Tiny Bloom wearable/portable breast pumps.
- Affordable Replacement: Lost or damaged shield? Replace just the shield instead of buying whole new pump.
Available Sizes
- 21mm: For smaller nipples (15-19mm diameter)
- 24mm: For medium nipples (20-23mm diameter) - most common size
- 27mm: For larger nipples (24-27mm diameter) - largest size
How to Choose Your Size
Measure your nipple diameter (not areola) after pumping when nipple is at its largest:
- Use a ruler or measuring tape
- Measure across the base of your nipple
- Add 2-4mm to your nipple diameter
- Choose shield size that matches this measurement
Signs You Need a Different Size:
- Too much or too little areola is pulled into tunnel
- Nipple rubs against sides of shield
- Pumping is painful or causes soreness
- Poor suction or low milk output
- Nipple looks damaged or irritated after pumping
- Shield doesn't create proper seal on breast

Why Proper Fit Matters
Using the wrong size pump shield is one of the most common reasons for:
- Low milk output (can reduce output by 30-50%)
- Painful pumping and nipple damage
- Poor suction and inefficient pumping
- Longer pumping sessions with less milk
- Frustration and giving up on pumping
The right fit creates optimal suction, protects your nipples, and maximizes milk output—making pumping comfortable and efficient.
